Weize Deep Cycle AGM 12 Volt 100Ah Battery, Maintenance-Free, 3% Self-Discharge Rate, 1150A Max Discharge Current, Perfect for RV, Solar, Trolling Motor, Wind, Marine, Camping and Off-Grid System

Great battery so far. It’s being used as an external battery for a ventilator while out and about and for emergency power for the patient. He can’t initiate breaths on his own so it’s essential for him to have power for the ventilator. The medical supply company only gives you a small 35ah battery that only last about 8-9 hours. If you want an optional bigger higher AH battery you have to purchase it on your own. This battery should last a full 24 hours before it needs a recharge that’s plenty of power for going out in the community and in the event we have a power outage and need backup power. It came well packaged and about 65% charged. The battery took a charge well and held its voltage after. I bought a group 29-31 battery box but I think I could’ve gotten away with a group 27 battery box however I’m not certain of that.We haven’t used it a ton yet but so far so good I ran the ventilator on the battery for over an hour and no issues and the battery provides stable voltage. I’ll update further if I have a reason to.

The batteries are of great quality and very affordable. I had bought 3 of them to chain to my solar generator. They worked awesome! I had so much more capacity on my generator. However, after a while (about a year), they were not holding 100% of the charge. I contacted the tech support of the solar generator company and they thought that the batteries (one or more) could have lost some efficiency. So, I contacted Weize about this issue and asked if they would be able to help. I also asked them about the warranty. The customer service was so outstanding. They got back to me right away even though it was a Saturday. They asked me questions about the problem, gave me suggestions to hopefully resolve the issue. I wasn’t expecting a refund or a replacement. I was just happy that their assistance was so prompt, professional and kind. But, eventually, they gave me an option of a refund or replacement. I chose a replacement because the batteries are great, no matter what. Sometimes, issues come up with any product or it can be a combination of different things (thus, the warranties). They set up the replacements promptly. I’m so looking forward to using these batteries again. I am so happy with the batteries, the warranty and the customer service!

These batteries for my husband’s motorized chair were such a great bargain. Price was excellent and he has already gotten many hours of use.

Fit well in the scooter and was partially charged to be able to verify functionality. Works well.

The battery was not operative after two weeks and when I requested a return they approved provided I bore the return postage cost of a battery weighing > 50 lbs.....1 star review.(I had bought a battery previously from the same vendor about 6 months ago and that became non operative after 6 months and outside the window of return but well below the life of a normal sulfuric acid battery)Well they reached out to me offering to help and after asking for a photographic evidence of a voltage measurement using a multimeter they approved a full return w/o having to return the battery.....5 star review (Good customer service, appreciated).(Though I will have to bear the cost of recycling= $13.00) - minus 1 star.

Was skeptical, but is working well with my Ion StormPro 35ACi Deluxe sump pump backup system. Shipping was quick, packaging was high quality. Very happy!

I received the order and put them the Jazzy mobile wheelchair. After charging for 14 hours unplugged and there was no charge. The wheelchair light would only turn on if plugged in. I submitted a request to return and followed the instructions that were provided by Amazon. UPS wanted $130 to ship the product back. The seller had instructions that if shipping costs more than $30 to call a phone number for other instructions.I called the number and was originally sent to voice mail. They called me back within 30 minutes and I gave them the order number and they told me that they would contact me with instructions within 24 hours on how to be refunded. They contacted within 48 via text and then email. They asked me to check the voltage with a meter and to submit to them the amps that the charger on the wheelchair produce. They wanted a picture of the voltage check. I check the voltage and sent them a picture of what they had requested.A couple days past and then they asked me to perform more tests and submit those pictures to them. Bottom line don't hassle with buying from this seller. You will get the run around and who know if you will be refunded the amount of the purchase.

Bought three of these a few months ago for my 36V 112lb Minnkota. Used them on a 4 day fishing trip recently where we fished 8-10 hours per day. They ran all day and had had power leftover at the end of the day. Definitely recomend.
